  2. Atrial tachycardia - Wikipedia

    en.wikipedia.org/wiki/Atrial_tachycardia

    Cardiology, electrophysiology. Atrial tachycardia is a type of heart rhythm problem in which the heart 's electrical impulse comes from an ectopic pacemaker (that is, an abnormally located cardiac pacemaker) in the upper chambers (atria) of the heart, rather than from the sinoatrial node, the normal origin of the heart's electrical activity.

  3. Supraventricular tachycardia - Wikipedia

    en.wikipedia.org/wiki/Supraventricular_tachycardia

    There are four main types of SVT: atrial fibrillation, atrial flutter, paroxysmal supraventricular tachycardia (PSVT), and Wolff–Parkinson–White syndrome. [2] The symptoms of SVT include palpitations, feeling of faintness, sweating, shortness of breath, and/or chest pain. [1]

  4. Paroxysmal tachycardia - Wikipedia

    en.wikipedia.org/wiki/Paroxysmal_tachycardia

    Paroxysmal tachycardia. Other names. Bouveret-Hoffmann syndrome. Specialty. Cardiology. Paroxysmal tachycardia is a form of tachycardia which begins and ends in an acute (or paroxysmal) manner. It is also known as "Bouveret-Hoffmann syndrome". [ 1][ 2][ 3]

  5. Paroxysmal supraventricular tachycardia - Wikipedia

    en.wikipedia.org/wiki/Paroxysmal_supra...

    Paroxysmal supraventricular tachycardia (PSVT) is a type of supraventricular tachycardia, named for its intermittent episodes of abrupt onset and termination. [3][6] Often people have no symptoms. [1] Otherwise symptoms may include palpitations, feeling lightheaded, sweating, shortness of breath, and chest pain. [2] The cause is not known. [3]

  6. Tachycardia - Wikipedia

    en.wikipedia.org/wiki/Tachycardia

    Tachycardia, also called tachyarrhythmia, is a heart rate that exceeds the normal resting rate. [1] In general, a resting heart rate over 100 beats per minute is accepted as tachycardia in adults. [1] Heart rates above the resting rate may be normal (such as with exercise) or abnormal (such as with electrical problems within the heart).

  7. Tachycardia-induced cardiomyopathy - Wikipedia

    en.wikipedia.org/wiki/Tachycardia-induced_cardio...

    antiarrythmic agents, diuretics, catheter ablation, pacemaker [1] Tachycardia-induced cardiomyopathy (TIC) is a disease where prolonged tachycardia (a fast heart rate) or arrhythmia (an irregular heart rhythm) causes an impairment of the myocardium (heart muscle), which can result in heart failure. [1][5] People with TIC may have symptoms ...

  8. Multifocal atrial tachycardia - Wikipedia

    en.wikipedia.org/wiki/Multifocal_atrial_tachycardia

    Cardiology. Multifocal (or multiform) atrial tachycardia (MAT) is an abnormal heart rhythm, [2] specifically a type of supraventricular tachycardia, that is particularly common in older people and is associated with exacerbations of chronic obstructive pulmonary disease (COPD). Normally, the heart rate is controlled by a cluster of cells called ...

  9. Lown–Ganong–Levine syndrome - Wikipedia

    en.wikipedia.org/wiki/Lown–Ganong–Levine...

    Individuals with LGL syndrome do not carry an increased risk of sudden death. The only morbidity associated with the syndrome is the occurrence of paroxysmal episodes of tachycardia which may be of several types, including sinus tachycardia, atrioventricular nodal re-entrant tachycardia, atrial fibrillation, or atrial flutter. [4]
